An unauthenticated remote attacker can exploit the vulnerability by sending PATH_CHALLENGE frames and manipulating the connection (e.g. by restricting the peer's congestion window size) so that PATH_RESPONSE frames can only be sent at the slower rate than they are received, leading to storage of path validation data in an unbounded queue.\n\n### Patches\nQuiche versions greater than 0.19.0 address this problem.\n\n### References\n[CVE-2023-6193](https://www.cve.org/CVERecord?id=CVE-2023-6193)\n[RFC 9000 Section 8.2](https://datatracker.ietf.org/doc/html/rfc9000#section-8.2)", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L" } ], "affected": [ { "package": { "ecosystem": "crates.io", "name": "quiche" }, "ranges": [ { "type": "ECOSYSTEM", "events": [ { "introduced": "0.15.0" }, { "fixed": "0.19.1" } ] } ] } ], "references": [ { "type": "WEB", "url": "https://github.com/cloudflare/quiche/security/advisories/GHSA-w3vp-jw9m-f9pm" }, { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2023-6193" }, { "type": "WEB", "url": "https://github.com/cloudflare/quiche/commit/ea7ecf39ae28ab24cf1785c1674dc2e8a076f9ca" }, { "type": "WEB", "url": "https://datatracker.ietf.org/doc/html/rfc9000#section-8.2" }, { "type": "PACKAGE", "url": "https://github.com/cloudflare/quiche" } ], "database_specific": { "cwe_ids": [ "CWE-400" ], "severity": "MODERATE", "github_reviewed": true, "github_reviewed_at": "2023-12-13T13:34:55Z", "nvd_published_at": "2023-12-12T14:15:07Z" } }
